The Nonsuch line of catboats is a series of popular cruising sailboats built between 1978 and the mid-1990s by Hinterhoeller Yachts in St. Catharines, Ontario. They are popular in North America, with over 950 boats built. The Nonsuch class was named after the Nonsuch that was the first trading vessel of Hudson's Bay Company, which in turn was named after the Baroness Nonsuch, a mistress of King Charles II of England.

The Nonsuch 22 is a Canadian trailerable sailboat, the smallest of the series of Nonsuch sailboats. It was designed by Mark Ellis Design and first built in 1984.
